(Intentionally creating new thread, not on one about broken d-u with Xorg.)

New Xorg, when successfully installed, will remove the "nv" driver for nVidia card.
It was long deplecated by nVidia company's support, but now completely deplicated from Debian sid.

So.. if you have been using "nv", you need to chose "noveau" or non-free "nvidia" driver.
I attemped to try "nouveau" before updating Xorg, but I failed.
(I use generic monitor, and it is not recognized. getting
"Screen not found" error.)
So I installed "nvidia" on my amd64 system with nVidia card.

There is a non-free solution, but I feel bad, I could be without non-free drivers more than a year...

I'm sure someone might consider an unofficial build of nv for those with old nVidia cards who cannot even use nouveau or the binary blob. I might attempt to build nv myself for one old machine with a TNT2 card. Where can I find instructions how to do that?

I have an old machine that uses onboard Geforce2 that I'm using as a media server. It works well with nv, it stutters a bit but can run glxgears and flash if needed. For it's purpose it functions well enough and I'd hate to loose that functionality. I'm going to put 'nv' on hold until we get a better soloution and I'll post if that breaks anything. For the time being I guess we can still get source and deb from stable.

I have uploaded a xsever 1.9.x compatible version of xserver-xorg-video-nv to frickelplatz.
Feel free, to use it.

thank you very much towo.

I removed nvidia binary driver.
Also, took time to try until vesa works...
for now I have two choices, of using "nv" from frickel, or using "vesa".
For my old 1280x1024 monitor using in 2D mode, they are both enough good.
Mark the thread as solved.

So no more nvidia-glx or nvidia kernel
sounds lousy.
I think I'll leave aptosid with the experimental nvidia as of old I installed, at least that works and looks good.
I don't think new xorg deserves installation from what is said here it is not good news at all!

the actual version of nouveau works well, my computer runs a custom kernel with nouveau enabled; previous versions have some problems playing video with nvidia GeForce 8400 GS, now have been solved.

My personal trick to deal with nvidia and nouveau modules is blacklist both in /etc/modprobe.d/00local, and specify the desired driver in Xorg.conf; this one will be loaded when xorg starts, even if blacklisted.

This URL contains a Debian source package for nvidia driver that works with this version of Xorg; if you want to compile it:
